POSTLESS LELGER BEQNDER.

Application filed January 21, 1924;. Serial No. 697,550.

To all 107mm may concern:

Be it known that l. @Eoin B. Hnnnrson, a citizen of Great Britain, residing' at Los Angeles, California, have invented a new and useful Postless Ledger Binder. of which the following is a specification.

This invention relates to ledgers and has for an object to provide a postless ledger binder.

Another object is to provide a ledger bind er of few and simple parts of such construction and arrangement that they will withstand rough and long use.

A further object is to provide a ledger binder having a minimum number of moving parts which are readily operable and very effective in clamping position, and in this connection. an object is to provide operative parts which cannot be dislodged and lost from the binder, and in which the operating` parts cannot be disconnected or overthrown during: operation.

An obiect is to provide an organized baclbone and clamping means in a ledger binder all of inexpensive, stock material.

An object is to provide a. ledger hinder having surface protecting means whereby to prevent marring of a finished desk, counter or other supporting plane upon which the ledger may be placed for use, filing or storing. and for the purpose of redncintr noise occasioned by and in placing and handling: the ledger on a supporting plane.

Other obiects and advantages will be made manifest in the followingspecification of an embodiment of the invention illustrated in the accompanying drawing, where- 1n:

Fig. 1 is a. perspective of the rear of the ledger back with leaves.

Fig. 2 is a perspective showing; the interior of the binder.

Fig. 3 is a longitudinal section of the binder: the leaves beine' omitted.

Fig. 4: is a transverse section showing the clamp bar fully retracted.

Fig. 5 is a transverse section showing' the bar in effective clamping position.

Fig. 6 is a perspective of the dismounted clamp bar.

Fig. 7 is a detail view of a corner structure of the back.

Fia'. 8 is a detail section of the hinge eye attachment. and an applied cover member.

The illustrated embodiment of the inven which extends tion comprises a shell having a backbone or panel 2, having longitudinal side flanges and parallel flanges or ends Ll, preferably all formed of a single :iece of sheet metal. The ends of the 'anges 3, are formed with flaps 5, bent around the ugstandinaend flanges 4i, to brace the same. The flanges 3, also have longitudinally extending, inturned lips G, and the corners of the ends 4. are recessed at 7. to receive the lips 6. This forms a rigid and substantial box or back-bone structure.

rlhe binder vis provided with a part fern ingrr a flat platen and this. as shown, consists of an inner platen device in the form of inwardly faced plates 9. in a common plane and which are shown as longitudinally spaced from each other. The plates 9, are rigidly secured in the back-bone and as shown have downturned side flanges 10, to one of which is secured a bearing` strip 1lx and to the other of which there is secured a bearing piece 1Q. Extending transversely across the back-bone of the binder is a subn stantial screw 13, one end of which turns in the bearingstrip 11, and the other end of which is reduced and projects through the bearing piece l2.

The bearing piece i2, is cut away to expose the square head 111-., of the screw 13, and the contiguous flange 3,isprovided with a. key-hole 13. for the insertion of a. key K, whereby the screw may be turned when it is desired to clamp leaves L. in the binder. The screw is prevented from endwise inovo ment between its bearing members 11.. and 12. which are rigid in the back-bone.

To effectively.7 clamp leaves L, in the binder there is mounted on 'the screw a slide 15, which is shifted alone; the screw when the latter is rotated. Bigidly connected to the slide is an upstanding` clamp bar 16, of suitable length and which extends longitudinally above the platens 9, upon which the back edges of leaves abutt and are aligned as shown in F ig. 5. Opposed to the shiftable clamp bar 16, is a rigid leaf support 17, longitudinally and contiguous to one side flange 3.

The clamp bar 16, when fully retracted recedes beneath the lip 6, of the outer side of the back-bone with respect to the fixed support- 17, and this provides for the insertion of leaves in a stack having a thickness about equal to the distance between the lips. To

provide for this recession of the clamp bar i6, this is shown as connected in ott-set relation to the slide l5; the bar having an angle ledere 1S, lying between the edges of the spaced platens 9, and heing attached to the slide l5. l

lt will be seen that the binder consists of tvvo relatively movable members; the screw 13, and the clamping device i6, mounted lthereon. lt will be seen also that ledger leaves L, may be securely fastened in place in the binder without the utilization of' any posts or other parts penetrating the leaves, and therefore enabling the ready insertion and removal of leaves in any position in the stack. Also, the moving parts are so connected that they ycannot become dislodged from the binder.

A it'eature of the invention consists of cushioning` means to reduce noise and also protect linished surfaces upon which the ledger may be imposed while in use or storage. Such means is shown as including rubber, or other cushion material, cushions 20, sui-tably secured preferably at the ends of the shell and projecting laterally and rearwardly so as to be effective in the diiierent positions of the binder.

The cover-backs C, of any suitable type may be hingedly 'connected to hinge-eyes 2l, provided along the flanges 3. These hingeeyes have ears 22, extending through the lips 6, and which are riveted at 23, to the 'flange 8.

The slide l5 extends endwise under the inwardly spaced platen plates and the ends ot the clamp bar 1G in a like manner extend over the platens. From this it will be seen that there are no posts or parts of any character passino' through or into the leaves, and that the lear space above the platens is clear tor the ready insertion of leaves in a uniform pile or stack.

The end portions of the slide and the clamp bar are spaced so as to receive the interpositioned platens, which. serve to guide the moving clamp device.

lVhat is claimed is:

l. A loose-leaf, book-binder having a backbox including lined, parallel sidewalls, an inner :false back having al platen tace tor leaf edges, a jaw shiftable laterally7 toward one side wall to clamp leaves thereagainst, and means lying between the box back and the inner false back for actuating the clamping jaW.

2. A loose-leaf, book-binder including' a back-box iaving longitudinal side walls, one olf which `forms a side support for leaves; an inner false back torni-ing a leaf-edge platen, a screw journalled between the back of the box and the false back and operable by a key insertable through one of said side Walls, and a clamp jaw in front of the platen face and connected to the screw for adjustment toward either of said Walls.

3. A book-lealil binder including a backboX having an outer back and an inner back with a platen face for leal edges, and longitudinal side Walls, a clamping bar in front of the platen face, and a transverse screw disposedv wholly between thefsaid backs and carrying and operating the har-laterally.

l. A book-leaf binder including a bookback box havingy a side wall forming a leaf support anda recessed wall opposite said support, a platen part for leaf edges, a leal"- clainping bar movable toward said support to clamp leaves and retraetablelinto the recessed wall, and means for moving said bar.

5. A book-leaf binder including a bookback box having parallelside Walls, an inner false back having a platen face for leafedges, a slide extending longitudinally under the platen back, a transverse screw for operating the slide, and a leaf-engaging means attached to the slide and extending over and along the platen.
